BS, a new Fiat with the red Paraflu UP may NEVER be filled, or topped up with blue paraflu, you will loose warranty immediately, and it will cause a massive mess inside the cooling system. i have already outlined this
On the other hand, as I wrote before, the Fiat company in Turin has send bulletins to their dealers worldwide, that it's totally safe to convert older Fiat engines, filled with blue or green Paraflu, to new style, long life red Paraflu Ultra Protection, after a good flush. very true the oposite is also very posible and wont cause a problem engine materials haven't changed all that much from the early 80s in fiats case anyway they have been using alloy heads since the 60s
So it's even no longer possible to buy blue Paraflu, only red U(ltra) P(rotection), wich can be used in EVERY Fiat. no we will still be able to buy it for quite a wile i'm sure
I have converted 4 Fiat's and Alfa's so far, no problems at all.
Another benefit is that the red Paraflu is very kind to aluminum, and the old style blue/green coolant isn't very good to aluminum, it eats it away after time, that's one of the the reasons you had to change it so often....!!!! can't see any proof of this it's water that eats your alloy not the (corrosion inhibitor)
